Abstract

An electrical installation, in particular a transformer, phase shifter or inductor, which includes a fluid-filled tank having side walls, wherein, for protection against bombardment and/or fragmentation effects, the side walls are formed in a bullet-resistant manner and are made of a material having a traction strength of greater than 1000 MPa, or wherein a bullet-resistant reinforcement made of such a material is provided, the outer side of which envelope the side walls.

First claim

What is claimed is:

1. An electrical installation, comprising:
a fluid-filled tank having side walls;
wherein one of:
(i) the side walls are formed in a penetration-inhibiting manner and are made of a material having a tensile strength greater than 1000 MPa to protect against effects of at least one of bullets and fragments and
(ii) a penetration-inhibiting reinforcement made of the material having the tensile strength greater than 1000 MPa envelops the side walls at an outside of the tank which protect against the effects of at least one of bullets and fragments; and further comprising:
a noise damping material arranged in an intermediate space formed by the penetration-inhibiting reinforcement which is attached to the side wall at a distance.

2. The electrical installation as claimed in claim 1 , wherein the electrical installation comprises one of a transformer, a phase shifter and an inductor.

3. An electrical installation, comprising:
a fluid-filled tank having side walls;
wherein one of:
(i) the side walls are formed in a penetration-inhibiting manner and are made of a material having a tensile strength greater than 1000 MPa for protecting against effects of at least one of bullets and fragments and
(ii) a penetration-inhibiting reinforcement made of the material having the tensile strength greater than 1000 MPa envelops the side walls at an outside of the tank for protecting against the effects of at least one of bullets and fragments; and

further comprising:
a noise damping material arranged in an intermediate space formed by the penetration-inhibiting reinforcement which is attached to the side wall at a distance;
wherein the electrical installation comprises one of a transformer, a phase shifter and an inductor.
